Normalized ratios (NR) obtained by Quantitative real time PCR (qPCR) for CNVR22. Y-axis shows the NR values obtained by qPCR, and X-axis represents the sample name of the detected 33 positive and 11 negative control samples. Samples with NR about 1 denote normal individuals (two copy), samples with NR about 0.5 denote one copy loss individuals (one copy), and samples with NR about 1.5 or more denote copy number gain individuals (≧three copy).
